Runtime Error Handling

Runtime errors are handled by the Dialog Manager. Runtime errors are non‑fatal, such as screen edit, or fatal errors.

If a non‑fatal error such as invalid user input occurs, the Dialog Manager displays an error message on the transaction screen. You can correct the error and continue processing the transaction.

If an application fails because of a fatal error, transaction processing terminates, and the error processing is as follows:

• The Dialog Manager performs all necessary rollbacks of the databases.
• CA Gen displays an error message screen that lists the appropriate runtime error messages.
• Pressing Enter from the error message screen causes CA Gen applications to terminate execution.
